I just purchased an XTM 24.7 Pro Pull-Start Engine. I am setting the needles for break-in according to the instructions, hold the throttle barrel open, then proceed to do 3 turns out from fully closed for the high speed needle and 8 turns out from fully closed with the low speed needle.
But I am running into a problem. When I back the low speed neddle out 8 full turns, the low speed needle screw comes out. It is not even in there.
What is a turn? Is it 360 degrees, or 180 degrees? I always thought a turn was 360 degrees, and if that is true, than I don't see how it is possible to back it out 8 turns. It is not a typo either, on the XTM website, the non-pro version of this engine is back out 7 and a half turns from fully closed, so 8 turns is correct.
The high-speed needle on the other hand will back out 3 full 360 degree turns just fine. This is confusing me even more.
Any help is greatly appreciated!
